to which it appertains to make anduse the sanie,'reference beinghad to the accompanying drawings and to the letters and figures of reference marked. thereon,which form a part of this specification. I

Myinvention relates to heaters, and more particularly to an apparatus wherein water conflnedwithin a radiator is caused tocireculateover' a heating unit in orderto main.-

tain the confined circulating water at a desired temperature, "the principal ob ect of the invention being to provide a' heater wherein the flow of'wateris restricted as it passes over and about the heating unit. In accomplishing this object I havepra... vided improved details of structure, the pie-- ferred form of whichis illustrated in theac- 3 compel ying drawings, whereinf .Fi'gure Iiis a vertical section of-a radiator.

equipped with my improved heater. "Fig. 11

is an enlarged perspective ofthe upper portion of -'the heater. Fig. III 1s a similar view of the lower portion of the heater.

Referring more in detail to the parts:

designates a radiator of any ordinary type except that 1t..has no connection with theusual seryice pipes. I

Extending from and communicating with the'lower and upper portion of one of: the end coils of the radiator are pipes 2 3, the former. ofwhich carries an upwardly open-' ingsocket 4 and the latter a downwardly opening cap 5. The socketi l has a central opening 6 in the bo'ttom'and a downwardly projecting c0llar.-7, the interior of which registers with the opening 6 and is .proig ided with screw threads 8, the upper portion of I the socket being interiorly screw threaded to carry a drum 9 which is also threaded into the upper ca 5 Threaded rnt'o the collar 7, and extending upwardly through the drum-9 to near the top thereof is adouble tube 10 which is spaced from the drum to form an annular chamber 11 and the annular chamber, 12 of which: contains aheating element 13, pref- Specification of Letters Patent.

era-biy' consisting of an ordinary resistance coil. The-lower end of the tube 1s closedby a cap 14, havlng apertures through which the switch plugs 13 may be projected tov close a circuit through thecoil.

Extendingthrough the interior of the Seated on the. bottoniof the socket a, and" extending around thetube 10, is a spiral 18 which fills the space between the tube and drum so thatiwatercirculating through the latter must pass in a circuitous path about the coil tube in order to pass upwardly through the drum, the convolutions of the spiral being preferably arranged so that the travel of the water is increased three-fold;

tom of the tubeth'rough the conduit-must pass circuitously around the-conduit inorder to reach the top of the tube',lwher.e it may mingle with the water from the annulus 11 and rise therewith through the'pipe '3 to the topof the radiator.

The upper ends of the spirals1S-1.) 'pref-' erahly tern'iinate at the side of-the drum opposite. the mouth of the conduit 15, so that jthe hot water rising from the annular-spaces controlled by the spirals will be delrvered away from the mouth of the conduit, so that relatively cooler water may betaken into the.

conduit to be delivered to the bottom of the heating tube.

Theradiator is provided with a filling cap 20 through which the radiator may be filled with water for circulationtherein, and the terminal wires'may' be connected with a suit able switch, although as the latter forms no .part of the present invention it-is not illustrated herein.

In using the heater, presuming the parts to be constructed and assembled as described,

Located within the tube and surrounding n when current is. turned into the heating unit Water within the-tube'anddrum is heated and tends to rise, the rising travelio f the water being retarded by the spiral so that it contacts the heating tube for a longer period than if the annular spaces were not obstructed; As the hot water rises through -ing its travel."v

I I the tube alnd dru'ni and passes into the pipe 3 to circulate within-the radiator, the cooler water flowing into the-bottom of the drum through pipe-2 and socket 4C rises ll'ljthe 'piral path about the tube and is heated dur- Owing to the fact that theinner annulus is of less area than the outer, water within the innen'a'nnulus 'will heatquicker and to a higher, temperature thany'the water in the- I outer annulus, andas the hotter water will 'tend to rise more rapidly, there is attendency'to' draw the cooler .water delivered from the outer annulus-down through the 'co'nduit'l5i so thatiwhile a circulation, is maintained throughoutthe entire=heater, an auxiliary circulationis maintained throughv the conduit and inner annulus, thereby inducin-g a quicker and more-eflective heatingcirculation of"t he,water than if the outer annulus alone.were-'used'.- Having thus described my invention, What 'I claim as new therein, and desire to secure by Letters-Patent,'is:- i

' l. A .heatercomprising admin, a hollow heating element contained within and spaced from the-sides of thedrum, and a conduit having its lower end'opening into the b(" ttoni ofrth'e heating element and its upper (and opening to the upper portion of the drum.

i having an intake chamber closed at onefend, 1

a conduit extending. through said chamber and having its opposite ends opening into the closed end of the heatingelement and above said element respectively, and means chamb'erftothe open end. thereof.

for inducing circuitous travel of fluid from the closed end'of said element to the open end thereof. r i

and having ports at the inner end thereof through which fluid may be delivered to the closed. end of said chamber and having its outer end turned laterally'over the open end 4 4, A heater, comprising aheating element, I A having an intake chamber closed atone end, ,a conduit extending through .said chamber of the heating element, and means contained.

within said chamber for inducing circuitous travel of fluid from the closed end of the 5. v Ina heater, a drum having intake and exhaust conduits at opposite 'ends, a hollow heating element contained within the drum and having a closed end adjacent the intake and an open end directed toward. the exhaust, a conduit-extending through the heating element, and having'ports opening into the closed end of said element and over the open end thereof respectively, for the purpose'set-forth. M a w '6. In a heater, a drum having intake and exhaust conduits at opposite ends, a hollow heating elementncontained within the drum and having ajelosed end adjacent the intake and an open end directed toward the exhaust, a conduit extending through the heatelement and between the heating element an ingxelementhaving ports openingin'to the closed end of said element and over the open ,jend thereof respectively, and splrals located within the annular spaces within the heatingthe druin, for the purpose set'forth.

7. In a heater; a-drum having intake and exhaust ports at opposite ends, a tubular heating element arranged centrally within the drum, a spiral arranged within the annular space between the heating element and drum, a conduit located centrally within the heating element with its upper end turned laterally over the discharge end of said spiral and having a port at its'lower end, and a spiralwithinthe heatin element having its discharge end arranged 'oppositely to the first named spiral, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
